lo @ZZ whom, it Netty concern:

Beit known that I, HENRYR. BAKER, a citi- Zen of the United States, residing at North Attleboro, in the county of Bristol and State of Massachusetts,haveinvented certainnewand useful improvements in Olasps, of which the following is a specication, reference being had therein to the accompanying drawings.

My invention relates to clasps adapted, primarily, for use upon watch and other chains, and has for Aits objects the ends commonly sought-by such devices.

To these ends my invention consists in the novel construction and combination of parts hereinafter described, and illustrated in the accompanying drawings, wherein- Figure lis arear elevation of my new clasp; Fig. 2, a side elevation of the same; Fig. 3, a transverse section of the saine in closed position on line ce t of Fig. l; Fig. 4, a similar section of the same, showing the lever and cam in open position in side elevation; and Fig. 5, a perspective view of the lining-plate.

Like reference-letters indicate like parts throughout the views.

My device consists of a U-shaped frame A, provided at its lower front extremity with an eye a, adapted to receive a link of the chain.

The rear face of the frame has an opening b to admit the lever c, which is pivoted by lateral studs d in depressions o in the frame o'n either side of the opening b. The lever is integral with and terminates in a cam e. A lining-plate B is soldered or otherwise ixed to the interior of the frame. This plate has an opening m through its front wall to allow passage therethrough of the cam and upon its rear side inwardly-projecting prongs n in horizontal alinement with the cam e. This f lining-plate assists in retaining the studs d 4c in their seats within the depressions o.

The disengaged position of my device is shown in Fig. 4E. To engage the same, the lever cis raised to vertical position against the lining-plate B, which action forces the cam inwardly against the prongs n, thus retaining the intermediate fabric.

The cam e is either cylindrical or spherical in shape.

Having described my invention, what I 5c claim is-' l. In aclasp,the combination ofa U-shaped frame having an eye and an opening with depressions upon opposite sides thereof, a U- shaped lining fixed within the frame and having an opening opposite the opening in the frame, said lining extending over said depressions, and a lever having lateral studs seated in said depressions and held against displacement by said lining and having a cam 6o portion working through said openings of the frame and lining.

2. In a clasp,the combination ofa U -shaped frame having an eye and an opening with depressions upon opposite sides thereof, a U- shaped liningt fixed Within the frame and having an opening coincident with that in the frame, a lever having lateral studs seated in said depressions and covered by said lining and having a carn portion, the lining being 7o provided with prongs extending toward and opposite the said openings.

In testimony whereof I have aflixed my signature in presence of two witnesses.

HENRY R. BAKER.
